Question

the area of the traingle formed by the vertices (x1,y1),(x2,y2)and (x3,y3) is ​

Answer 1

Solution

area formed by the vertices(x1,y1),(x2,y2)and (x3,y3) is

$\frac{1}{2} \times ( {x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)} \: )$

Answer 2

• If the Vertices of Triangle ABC are A(x₁ , y₁) , B(x₂ , y₂) , C(x₃ , y₃)

Then The Area of Triangle ABC = 1/2 × [x₁(y₂- y₃) + x₂(y₃ - y₁ ) + x₃(y₁ - y₂)]
